- My talk from @bioctrl.bsky.social about the physical origin of agency is uploaded here: youtube.com/watch?v=YY21... TLDR: noise equals control. Nature is constantly sampling control trajectories via noise
- This solves the conceptual `agency-body' problem of dualism, i.e. reconciling a mechanistic description of biology with an agential one
- It also solves a conceptual problem in the field theory of stochastic systems, which is the physical interpretation of the `momentum' field that is introduced as a Lagrange multiplier, or via other abstract methods. The field is a control strategy. Agency is part of NatureJul 9, 2025 19:27
- In the talk I explain it all in simple language, and reinterpret stochastic resonance & Brownian ratchets with the noise-control mapping.
- The talk is based on my recent preprint arxiv.org/abs/2503.15670 written in an abbreviated manner for theoretical physicists. I am expanding the preprint to full article length and will update the arXiv soon.
- I will be around at StatPhys and Molveno if you want to chat! ( I am giving a talk about random languages in a ML session )
- The arXiv preprint is updated to a full-length article (10 pages + 7 pages SI).
